To all whom it may concern: I

Be it known that I, RICHARD ANTON Gown, a citizen of the United States, and

a resldent of San Antonio, in the county of .Bexar and State of Texas, have'invented a new and Im roved Automobile-Pump, of which the 0 owing is a full, clear, and exact description. Amon the principal objects which the present invention has in view are: to provide a pumping attachment which may be readily and quickly mounted-upon a driving wheel of an automobile; to provide a pumping' apparatus which is held in operative position by the weight of the automobile during the adjustment and subsequent operation; and to provide a structure which is economical, simple and durable.

One embodiment of the present invention is disclosed in the structure illustrated in the accompanying drawings, in which like characters of reference denote corresponding parts in all the views, and in which-' Figure 1 is a side elevation of an automobile driving wheel shown in conjunction with a pumping apparatus constructed and arranged in accordance with the present invention; Fig. 2 is an edge view of an automobile wheel showing in conjunction therewith a fragment of an automobilev raised upon an ordinary lifting'jack, and with a pumping apparatus constructed and are ranged in accordance with the present invention; Fig. 3 is a side view'of the pumpi gapparatus constructed in accordance with the resent invention, and assembled in its knoc -down or carrying position; Fig. 4 is a' detail view in section showing the mounting of the pump upon the base plate; Fig. 5 is a detail view in section of the crank pin carrying arm and expansible connection; and Fig. 6 is a front view of the expansible connection.

The present apparatus. comprises an air pump of any desired style or operation. The pump casing 7 is mounted upon a base 8, which is pivotally 'mounted' upon a bolt 9 extended through up-turned ears 10, 10 of \a holder 11, which is means of a -bolt 12upon a-riding plate 13. The plate 13 is let into abase plate 14 when the same ismade of I accompanying drawings, and secured thereto .by means of screws'15, 15. When the base 55 plate- 14 is constructed from metal the late 13 may be mounted npon seating pads of arrangement is to the said plate pivotally mounted by wood, as shown in the shown, to produce at usual construction. the plate 13 are cars 16, 16 in which is piv- Extended upward from otally mounted a pivoted latch 17 adapted to fall into and seat in a groove or slot formedin the side of the holder 11.

The purpose of the above construction and permit the pumpcasing 7 to rock within the holder 11, due to the throw of the piston rod of the pump as the same is moved about the center of the wheel of the automobile to which it is attached. Also, it'is desired that the holder 11 may be so disposed with reference to the plate 14 that the casing 7 may be laid lengthwise of 14 when the apparatus is knocked down for storage. It is to prevent the holder 11 from rotating upon the bolt 12- that I have provided the latch 17. Then the latch 17 is in engagement with the holder "11 the casing 7 is in pumping position. The

piston rod 18 of the pump is provided with a bearing plate 19 to-receive a crank pin 20.

The crank pin 20 is extended from a projection 21 which further formsa guide for the seating of an expansion plate 22. The

pin 20 and projection 21 are carried upon a plate 23. The plate 23 is provided in the lower end with an opening 24 octagonal in shape to fit a cap nut 25 of a wheel 26. The shape and size of the opening 24 may be altered to suit the size and shape of the cap nut usedon any individual automobile. The plates 22 and 23 are both provided with slots 27, 27 The plate22 is also provided with a slot 28 which extends at each side of and is guided by the projection 21.- Extended from the plate 22 is a screwthreadedbolt-like projection 29 upon which is screwed a nut 30. When the plates 22 and 23 are assembled the sides forming the slot 28 are extended at each side of the projection 21 and the projection29 is inserted through the slot 27 in the plate23, in which position the nut 30 is screwed upon the said projection'29, looking the plates 22 and 23 together. The abuttlng faces of the plates 22 and 23 are serrated to form teeth, 31 which mesh when the said plates are drawn together by the nut 30. The upper end of the plate 22 is provided with ears 32, 32 upon which are pivotally mounted links 33, 33 to receive'thrustwods 34, 34. The links 33, 33 are formed, as the connection between the rods 34, 34 and the plate 22', aflexible knuckle joint whereby the rods may assume anyposition relative to the plane of the wheel 2-601 of the spread of the said rods 34, '34. The rods 34,- 34 may be formed in any desired manner, thatshown 1n the pres ent drawings as preferred by me having a break joint whereby the rods 34 may be folded to occupy less space in packing. At the free end the rods 34, 34 are provlded with yokes 36, 36 adapted to extend over the spokes of the wheel 26 or the telly of the same.

' Extendedthrough the slots 27, 27 is'an anchor bolt 37, on the end of which is provided a hook 38 adapted to extend around and engage one of the s okes of the wheel 26. The end of the bolt 3 is screw threaded, upon the threaded end whereof is mounted a wing nut 39.

The base plate 14 is elongated, as shown in Fig. 20f the drawin s, near the one end of which is mounted t e holder 11 and the' pump casing 7 It is intended that the plate 14 shall be long enough to receive the foot of a jack 40. Between the holder 11 and the jack is mounted on the plate a scoop-.

. passed over .the nut 25. The rods 34' -are 35 then unlimbered to extend so that the yokes .36, engage convenient spokes of the wheel 2t resting in the crotch of the joint between the said spokes and the telly of the said wheel. The rods 34 are then strained, the nut 30 having been loosened so that the plates 22 and 23 are not held in rigid contact. It

is by means of the plate 22, by raising and lowering upon the plate 23, that the adjustment ofthe combined plates 22 and 23 and the rods 34, 34 is made to conform to the wheel 26. This having been accomplished the bolt 37 is extended until the hook 38 passes behind the spoke with which the plates 22, 23 are alined. By turning the nut 3!) the bolt 37 is caused to draw upon the spoke with which it is connected. Continued operation of the nut- 39 tightens all of the connections by reason of the tripod arrange ment of the plates 22, 23 and rods 34, Ell. The apparatus is now in position to operate. The operation consists in first lifting, by means of the jack 40, the wheel 26 from the shoe 41. The engine is now started and the speed of rotation of the wheels is regulated by. means of thespeed gears to operate the pump rapidly or slowly, as may be desired.

vided with a flexible pipe connection 42' whereby it is attached to the hollow tubing 1 of the automobile tire.

It will be seen that'by meansfof this construction and arrangement a tire may be rapidly expanded andthat the force of expansion may be far in excess of that produced by manual. operation. By using a speed attachment-of any of the well known types the bursting of tires due to excessive pressure may be avoided.
